and in the six years that we served together, i as majority leader, bob dole as minority leader, never once did a harsh word pass between us, although we differed on many issues, we debated vigorously on the floor of the senate, but it was not personal and we had dinner a couple times a week to talk about the issues and the problems that we had, and life in general. i think that's missing now, unfortunately. >> so i mean, who do you -- i don't know if blame is the right word, but how do you account for this idea that compromise is a dirty word in some quarters? is it tea party, is it extremes in either party? who is it? >> i think it's a combination of many factors, and i'm not an expert on this. i don't pretend to have all of the answers. but first, you now have redistricting which means that the vast majority of house members are elected in safe seats so the crucial election is not the general election, it's the primary election, and as we know in primaries, there's low participation which gives a hugely disproportionate power to the rigid extremes on both sides. that makes it very difficult.
